The Roper Center for Public Opinion Research is a special place where people keep a lot of information about what other people in the world think about different things.
Imagine that you and your friends are playing a game of "Would you rather?" You might ask questions like "Would you rather have ice cream for dinner or broccoli?" or "Would you rather be a superhero or a princess?"
Well, the Roper Center is kind of like that game, but for grown-ups. Instead of silly questions, they ask people very important questions about things like politics, the environment, and social issues.
Then, they keep track of all the answers people give and put them into special computers so that they can look at them later. This helps the people who work at the Roper Center figure out what the majority of the population thinks about different issues.
This information is really important because it can help politicians and other leaders make decisions that will make the most people happy. It's kind of like asking a big group of people what they want for dinner and then making the most popular choice.
So, the Roper Center is a very special place that helps people understand what other people think about very important things in the world.
